Abstract

The invention discloses a method for processing double key grooves with a distribution of 180° at the shaft end of a large motor, which includes the steps of installing the rotor, installing and adjusting tooling, processing the first key groove, processing the second key groove, and the first key groove and the second key groove After processing, recheck the symmetry of the first keyway and the second keyway with a dial indicator to further confirm the machining accuracy of the first keyway and the second keyway. In the method for processing the double key grooves distributed at 180° at the shaft extension end of the large motor of the present invention, the calibration reference plane adopted in the process of processing the first key groove and the second key groove is the same plane on the same alignment tool, with small error and high precision , which can ensure the 180° rotation accuracy of the rotor, thereby ensuring the symmetry of the two key slots.

Description

technical field [0001] The invention relates to a keyway processing technology, in particular to a double keyway processing method with 180° distribution of the shaft extension end of a large motor. Background technique [0002] The shaft extension end of the motor, that is, the shaft extension end of the rotor, is the part that is connected to the user. The quality of the keyway processed on the shaft extension end will directly affect the quality of the entire motor. The keyway on the shaft extension end has high technical requirements and is difficult to process. . Machining the keyway on the shaft extension of a large motor is a common thing. The keyway has a depth and length and is generally processed by a milling cutter. The processing technology of a single straight keyway is very mature. Straight keyway is not so simple. A single straight keyway has requirements for dimensional accuracy and symmetry of the keyway, and there are also requirements for symmetry between...
